I've a kind of specific question that I was unable to find an answer for in the official documentation of VMware or on some other very useful threads here on this platform, so here it is:
I've got a host using ESX 6.0 with 2 sockets, each has 6 cores with HT. So in total I'm having 12 cores and 24 Threads on that Hardware.
It is running 10 VM's. I've allocated 34 cores (I know thats bad, but can't change that right now).
However, I'm experiencing serious problems with 1 of the VMs, that has 8 cores assigned (2 x 4).
I'm aware of how hyper threading is working and that in an ideal workload an HT-Core would have around 50% of the performance of an "real" core.
So here is my question: Would I benefit from using CPU affinity to make sure, that this Server has 8 "real" (=faster) cores, instead of letting VMware handle cores?
